Abstract

A novel optical-fiber version of Young's interferometer using a low coherent light source and a linear CCD detector is described. With its unique, simple structure, this interferometer greatly reduces the spatial coherence mismatch from which other electronically scanned 'white-light' interferometers suffer. Experimental results are presented for the use of this interferometer as a strain or temperature sensor with large dynamic range.
